Hi @Jonesy Cat
NSG Flow logs should show the IP address and port of the client on inbound traffic.
Network security group (NSG) flow logs is a feature of Azure Network Watcher that allows you to log information about IP traffic flowing through an NSG. Flow data is sent to Azure Storage accounts from where you can access it as well as export it to any visualization tool, SIEM, or IDS of your choice.
NSG Flow Log Common use Cases:
Network Monitoring
Usage monitoring and optimization
Compliance
Network forensics & Security analysis
